qemu: use MiB instead of Gib for virtio-fs cache size

Browse Source 
QEMU supports finer-grained units than GiB.  Change the cache size to
MiB so users have more control over the cache size.

Note that changing the semantics of the CacheSize field is fine because
there are no users of this API yet.  kata-runtime will be the first
users and prefers MiB instead of GiB.
